A vulnerability recently exposed in Diffie-Hellman key exchange for TLS is potentially serious. However, it can be mitigated by doing the following on all of your TLS/SSL enabled systems:
Due to the nature of this vulnerability, we do not currently have signatures for detecting an exploit attempt in progress. However, we are actively researching methods of detection that can be rolled out to our sensors.
The mechanics of this exploit require Man-in-the-Middle access to the network between the client and server, which makes the largest potential threat either internal users or outside users accessing an insecure network.
The below post on the Logjam attack outlines the configuration changes needed to generate a unique 2048-bit Diffie-Hellman group on common servers applications and will allow Server Test for HTTPS web servers.
